Broadway scion Eric Nederlander’s wedding came to a close with a giant fireworks display, and now the marriage is ending the same way.

Nederlander – best known as the first Mr. Jessica Seinfeld – has been accused of domestic violence and ordered to stay away from his wife of three years.

Manhattan Supreme Court Justice Harold Beeler signed an order of protection last week directing Nederlander, 42, to stay away from Lindsey Kupferman and her place of employment. The order also tells him to “refrain from assault, stalking, harassment, menacing, reckless endangerment, disorderly conduct, intimidation or threats.”

He is allowed to visit their 4-month old daughter, Mira, three times a week, when Kupferman is not around.

It’s unclear what precisely led to the judge signing the order, but a source said police had been called to the couple’s West 13th Street home on Nov. 30 and Dec. 14. No arrests were made.

Kupferman’s lawyer, Robert Smith, said the judge had signed the order “based upon a finding of danger to person or property and domestic violence.”

A rep for Nederlander – a producer whose family gave their name to the Nederlander Theatre – said “the claims in the order of protection are false,” and that he’s hired lawyers to appeal.

The rep pointed the finger at Smith for his attempt “to try the case in the media.” He said the case should be heard in the courts in “a dignified manner.”

Smith said he filed the sensational divorce on behalf of “persons anonymous,” and that he was only speaking out after seeing a Page Six item yesterday that said the “unlucky in love” Nederlander had agreed to leave their three-bedroom condo so his wife and daughter could stay there.

“I did not plant the item in the New York Post. It was either Mr. Nederlander or his minions,” he said.

Nederlander has refused to clear out of the triplex.

Smith said that Kupferman and their baby have been staying with her parents since they left on Dec. 14 – the date of the last police call.

Beeler ordered Nederlander to clear out earlier this month, but allowed him to stay temporarily while his lawyers appeal the ruling.

Nederlander and Kupferman met back in 2000, two years after he was jilted by his new bride Jessica Sklar, who had fallen for funnyman Jerry Seinfeld.

Kupferman, a psychologist, told The New York Times’ Vows section they were a perfect match. “Emotional baggage is my business,” she quipped.

The pair were slated to tie the knot at the Breakers hotel in Palm Beach in September 2004, but the wedding had to be put off after Hurricane Frances.

They walked down the aisle on Nov. 21, and Kupferman – also a professional singer – crooned, ” ‘Til There Was You.” The ceremony was topped off with fireworks over the ocean.
